Know What Interior Design Really Costs Per Square Metre

When you ask an interior designer worldwide how much a project will cost, the answer is almost always "it depends." And it does—on scope, materials, location, and finish level. But having a per-square-metre benchmark gives you a realistic starting point for budgeting. The Interior Cost Per Sqm Estimator on ToolDeft calculates the approximate cost per square metre for your interior design project based on the scope of work, material tier, and location within.

How the Estimator Works

Start by entering the total floor area of the space being designed. Then select which elements are included in your scope: flooring, wall treatments (paint, wallpaper, or panelling), ceiling work (POP, gypsum, or suspended), built-in furniture, loose furniture, lighting, window treatments, and accessories. For each element, choose a quality tier: economy, standard, or premium. The tool applies market rate ranges for each element at each tier and calculates a combined cost per square metre.

You can also select your city—Lagos, Abuja, Port Harcourt, Kano, Ibadan, and others—to apply a location adjustment factor. Interior design costs in Abuja tend to run 10–15% higher than Lagos due to transportation costs for materials, while cities like Ibadan and Kano are typically 15–20% lower.

Who Is This Tool For?

Property developers need per-sqm interior fitout costs when preparing pro-formas for new projects. Knowing that a standard-tier residential interior runs roughly 80,000–$120,000 per sqm in Lagos helps them price apartments accurately. Homeowners can compare their designer's quote against market benchmarks. Interior design firms use the estimator to set client expectations early in the engagement. Real estate agents advising clients on renovation budgets benefit from quick, data-backed estimates.

Practical Example

A young professional in Lagos has purchased a 95 sqm apartment and wants a full interior design fitout. She opens the Interior Cost Per Sqm Estimator and selects standard-tier everything: tiled flooring, painted walls with one accent wallpaper wall, POP ceiling with cove lighting, a custom TV console and shoe cabinet, mid-range loose furniture, and basic curtains. The tool estimates $105,000 per sqm, giving a total project budget of approximately 9.975 million USD.

She then experiments by upgrading the flooring to premium (engineered wood) and adding premium lighting fixtures. The estimate jumps to 145,000 per sqm, or 13.775 million USD total. This helps her decide which elements to splurge on and where to save, arriving at a realistic budget before her first meeting with a designer.

Understanding Cost Drivers

Flooring is typically the single largest cost component. The difference between basic ceramic tiles ($15,000/sqm installed) and imported porcelain or hardwood (45,000–$80,000/sqm) can double the overall budget. The estimator makes this impact visible.

Built-in carpentry (wardrobes, TV units, kitchen cabinets) is the second major driver. Custom joinery in quality MDF or plywood with good hardware adds significantly but also adds the most perceived value to the space.

Ceiling work varies dramatically. A simple flat POP ceiling costs far less than an elaborate stepped design with concealed LED strips. The estimator lets you toggle between options to see the impact.

Tips for Using Cost-Per-Sqm Estimates

Remember that per-sqm costs are averages across the entire floor area. Kitchens and bathrooms cost more per sqm than bedrooms because of their fixtures and waterproofing. The estimator weights this appropriately if you specify room types.

Always add a 10% contingency on top of the estimate. projects almost always encounter unbudgeted costs—electrical rewiring, plumbing fixes, or material substitutions due to stock-outs.

Use the estimator's output as a conversation starter with designers, not a final budget. Every project has unique requirements that a general estimator can't capture perfectly.
